perf test: Update parse-events expectations to test for multiple events

With PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE events opening on
multiple PMUs, the test expectations need updating to test for
multiple events. TODOs are added to document existing hybrid perf
bugs.

Tested on hybrid alderlake and non-hybrid tigerlake.
